MATCH.

To all whom it may concern Be it known that 1, WILLIAM A. FAIR- BURN, a citizen of the United States, and

resident of Short Hills, in the county of.

-a match hai'ing a splint possessing non-combustible and non-glowing characteristics, whereby when the match is ignited and the flame of the head-composition and burning substance extinguished the splint not only is ,devoid of spark and afterglow but its original size and shape are unimpaired. To this end, match splints are impregnated with a solution of materials which impart noncombustible, non flaming and non glowing properties to the splints. The match stoc may first be treated with the solution and the splints be cut from the impregnated stock; or the treatment of the splints with the solution may be eflected after they have been cut from non-impregnated stock. The impregnated splints are dipped into and thus permeated to the desired extent with an inflammable substance, such as molten parafiin wax, and are then headed with ignition composition in the usual manner. lVhen the matches thus produced are ignited the fire passes through and along the splints consuming practically only the therein contained parafiin or inflammable matter without burning the body of the splints, and, as above mentioned, when the flame is extinguished the splints are devoid of spark or afterglow.

A mixture of materials which well imparts the desired non-combustible, non-flaming and non-glowing characteristics to the splints I acid phosphate (NI-1,) HPO,500 parts and ammon'um sulfate (NH,),SO;-100

parts, dissolved in water 3000 parts, preferably in the order justgiven. This solution is heated to about 180 Fahn, and the match splints are dipped or immerged therein for a sufiicient period of time until the requisite impregnation of the splints has been effected.

It is to be understood that the described comprises, for example, ammonium Specification of Letters Patent.

whereby when the match is ignited the fire which passes through the splint does not impair the size or shape of the splint but consumes practically, only the said inflammable substance, and whereby when the flame is ex' tinguished the splint is devoid of spark or afterglow. v

What I claim is 1. -A match having a splint of permeable material with whichis incorporated a substance which renders said material non-combustible, non-flaming and non -glowing throughout its length, and with which ma-' terial is incorporated in addition to the firstnamed substance a substance'which burns with flame along the non-burning body of the splint.

2. A match having a splint of permeable material possessing non-combustible, nonflaming and non-glowing characteristics and permeated to a substantial extent with an inflammable substance, whereby when the consumes practically only the match .is ignited the fire which ,passes.

through and along the splintdoes'n ot-impair the size or shape of the splint but saidiirfiammable substance. 1 I 3. A match having a splint of permeable material impregnated with a mixture of am- -monium,acid phosphate and ammonium sulfireproofing and non-glowing properties may I be imparted to the splints by materials other, than those above described, without deextent with para 11.

fate in such proportion as to render the splint non-combustible, non-flaming, and

non-glowing, .and permeated to a substantial extent with an inflammable substance.

4. A match having a splint of permeable material impregnated with a mixture of am:
